             Summary: Submission only server
                 Key: JAMES-4171
                 URL: https://issues.apache.org/jira/browse/JAMES-4171
             Project: James Server
          Issue Type: Improvement
          Components: SMTPServer
            Reporter: Benoit Tellier


h3. Context 

I end up having to provide a submission only server for one of my customer.

Problem: James bundles together the MX and submission role thus always accept email of remote users addressed to local users.

This unorthodox behaviour is not a problem when combining both roles (though surprising!) however not being able to say "only authenticated users here" prevents implementing the aformentionned use case

h3. Proposal

Add auth.required configuration option in SMTP

If true, then discard unauthenticated senders.

This shall be the documented + recommended value however for retro-compatibility I propose to keep the legacy value as a default value.
